JAVA设计模式（02）：创建型-抽象工厂模式（Abstract Factory）

工厂方法模式通过引入工厂等级结构，解决了简单工厂模式中工厂类职责太重的问题，但由于工厂方法模式中的每个工厂只生产一类产品，可能会导致系统中存在大量的工厂类，势必会增加系统的开销。此时，我们可以考虑将一些相关的产品组成一个“产品族”，由同一个工厂来统一生产，这就是我们本文将要学习的抽象工厂模式的基本思...

JAVA设计模式（01）：创建型-工厂模式【工厂方法模式】(Factory Method)

简单工厂模式虽然简单，但存在一个很严重的问题。当系统中需要引入新产品时，由于静态工厂方法通过所传入参数的不同来创建不同的产品，这必定要修改工厂类的源代码，将违背“开闭原则”，如何实现增加新产品而不影响已有代码？工厂方法模式应运而生，本文将介绍第二种工厂模式——工厂方法模式。1 日志记录器的设计&nb...

java设计模式2--抽象工厂模式（Abstract Factory）

抽象工厂模式（别名：配套）提供一个创建一系列（相互依赖）对象的接口，而无需指定它们具体的类。概述当系统准备为用户提供一系列相关的对象，又不想让用户代码和创建这些对象的类形成耦合时，就可以使用抽象工厂方法模式来设计系统。抽象工厂模式的关键是在一个抽象类或接口中定义若干个抽象方法，这些抽象方法分...

java设计模式1--工厂方法模式（Factory Method）

工厂方法模式（别名：虚拟构造）定义一个用于创建对象的接口，让子类决定实例化哪一个类。Factory Method使一个类的实例化延迟到其子类。概述当系统准备为用户提供某个类的子类的实例，又不想让用户代码和该子类形成耦合时，就可以使用工厂方法模式来设计系统。工厂方法模式的关键是在一个...
